Theoretical particle physics research - simulations and theory

In summary, the conversation discusses the differences between research in lattice quantum chromodynamics (QCD) and other areas of theoretical particle physics. It is noted that lattice QCD involves a lot of computational work, while research in other areas often involves a mix of numerical simulations and pen-and-paper calculations. The speaker expresses a preference for the more formal side of theoretical physics, but acknowledges that it requires a strong mathematical background. It is also mentioned that funding for research in this field is not an issue, but rather the rarity of individuals with the necessary skills and knowledge.

I have just embarked upon a PhD in Lattice QCD. I'm wondering, what is research like in other areas of theoretical particle physics? Lattice is highly computational and fairly light on theory so it seems a lot of people in the field spend quite a bit of time making/updating and running large amounts of code. Does most research in theoretical particle physics involve numerical simulations to a large extent? Is there anyone that still does things with good old pen and paper apart from maybe string theorists?

I say this because I guess I like the formal side of things more than the computational part which I find kind of mechanical. But it seems that most research in theoretical particle physics involves a fair amount of numerical simulations, so it is kinda inescapable.

The problem is that working 'on the more formal side of things' takes a tremendous amount of mathematical background these days, the equivalent of several years of graduate math classes. Even though there are not many people doing this stuff relatively, that is not because of money* but because people who have a sufficient background are rare.

*If formal theoretical physicists could not find funding, then how could any mathematicians find funding at all! Unless this were all some kind of political game with semi-arbitrary rules and initial conditions, which it is.

As a scientist with a background in theoretical particle physics, I can say that research in this field involves a combination of both simulations and theory. While some areas, such as lattice QCD, heavily rely on computational simulations, other areas may focus more on theoretical calculations using pen and paper.

In general, theoretical particle physics research involves developing and testing theories to explain the fundamental particles and forces that make up our universe. This can involve using mathematical models and equations to make predictions about the behavior of particles and their interactions. Numerical simulations are often used to test these theories and make predictions that can be compared to experimental data.

However, there are still many areas of theoretical particle physics that rely primarily on theoretical calculations and do not require extensive simulations. For example, string theory and certain aspects of quantum field theory involve a significant amount of mathematical analysis and do not rely on simulations.

It is important to note that both simulations and theory play crucial roles in advancing our understanding of particle physics. While simulations can provide valuable insights and test theories that may be difficult to study experimentally, theoretical calculations can also provide important predictions and guide experimental research.

Ultimately, the specific balance between simulations and theory in a particular research area may vary, but both are essential tools in advancing our understanding of the fundamental building blocks of the universe. So, if you are more interested in the theoretical aspects of particle physics, there are definitely opportunities for you to pursue research in that direction.
